Retrospective Analysis on 1367 Cases of Localized Vitiligo

Objective To summarize and analyse clinical characteristics of progress of localized vitiligo.Methods Questionnaires were carried out to collect the clinical data on 1367 patients with vitiligo.Statistical analysis was completed.Results 782 cases of localized vitiligo(57.21%) progressed to sporadic vitiligo,which needed an average of 4.701 years;199 cases of localized vitiligo(14.56%) progressed to the acral vitiligo,which needed an average of 6.721 years;191 cases of localized vitiligo(13.97%) progressed to segment vitiligo,which needed an average of 2.03 years;and 33 cases of localized vitiligo(2.41%) progressed to generalized vitiligo,which needed an average of 7.18 years.Only 162 cases of localized vitiligo(11.85%) remained unchanged.Conclusion Vitiligo is a progressive disease.It is concluded that most localized type vitiligo is the early stage of non-segmental type,but a small number of cases belong to the early stage of segmental type.A rapid progression of vitiligo is more likely to be observed in patients affected by other disease or factors.Most patients with localized vitiligo progress to sporadic vitiligo.The localizad vitiligo needs seven to eight years.Therefore,vitiligo need to be treated as soon as possible to control the development.
